    XK conundrum - 4.2 or 5.0

    Morning All
    First post so please treat me gently....
    A little history of how I come to be here - I have always been a car enthusiast and over the last 15 years have been in a position to indulge in some “toy” cars since my daily driver has always needed to be sensible. The last toy (Lotus Elise) went a couple of years back when my son started driving and 4 cars on the drive was full enough!
    However a change in circumstances means that I no longer need a “business” car, just something to commute in and enjoy at weekends. Given that both offspring now have their own cars, and lives (!) I reckon it’s time to have something interesting as my everyday car.
    Budget was set at c£10k - I could spend more, but less on the car means more for other things!
    Having toyed with the idea of a Boxster - I’ve never been a Porsche person - an X150 coupe is my ideal choice.
    Cue extensive research of buying guides/forums/etc
    Search started last month, and I narrowed it down to an 07 4.2. Good history, enthusiast owned for last 5 years, 65k miles, £11k. Made contact with garage who look after it and all good. Only downside is that it’s silver which I don’t find that inspiring...
    Then what happened? I discovered that early facelift 5.0 cars are available for c.£14k.....I’m not that bothered either way about the exterior but I do feel that the interior looks a lot more current and the extra equipment would be handy....and my research suggests they are a better car all round..?
    Found one I like (grey) - one owner from new and complete history - but I’m probably going to miss it as someone viewing it this weekend...so I’m now going full circle back to the 07 car.....which I reckon I can get for near to £10k.....but..should I hold out and wait for another 5.0 to appear.....

    As you will have gathered I have entered the frustrating stage of the sourcing process....I guess I’m just looking for any views/suggestions etc that might help me re-focus!

    Previous performance purchases were Westfield, Chimera, Elise, MX5, Elise and I know I experienced this same situation with those!

    I apologise as I know lots of this has probably been covered before but hopefully some kind soul will be prepared to share their wisdom!!

    TIA

    Welcome to the forum Chrisbin, enjoy. The difference between the 4.2L and 5.0L is night and day, if you can find a good one in your price bracket then that would be my choice.

    Which ever you go for, check that all the electrics work as they should and don’t be fobbed off with, “they all do that”.

    Good luck with your search.

    For my two pence worth and not having driven a 5 litre I find the 4.2 XKR more than enough car for me.
    Realistically I'm now in the "retired" bracket so most of my trips are done with the roof down and cruising but I do enjoy a run up on to the moors now and then without the limiter sat next to me.
    Good luck in what ever you decide

    Thanks for the input.
    From what I understand a 5.0 Na has similar performance to the 4.2R.... but to be fair I’m really not worried about the performance (must be getting old), it’s the interior look and reports of improved quality that interest me....but I’m still not convinced those are worth the extra outlay...

    For me 4.2 in terms of performance and economy is fine; I don't feel the need for a bigger engine or a fraction off 0-60.

    So it comes down to looks. The later interiors do look a bit nicer with the chrome bits but there's not much else in it as far as I can see. Externally I like the 4.2 but I appreciate that's a personal thing. If I liked the look of the 5.0 better I'd buy that and bear the slight extra running cost.

    The only thing I don't like about the performance, or rather driveability, of the 4.2 is that driving normally in 'D' it doesn't kick down to overtake as I want - you put your foot down and nothing happens. So to overtake safely you need to flip the paddles down one or even two gears. 'S' is just silly; it will make you go faster but it stays permanently one gear lower even when coasting; god knows what it does to the mpg. It's such a shock going from 'D' to 'DS' that I never use it to overtake as it feels it will put me in a hedge. And that's after owning 3 TVRs! Is 'S' in the 5.0 equally nuts?

    That’s pretty much the point for me - I know that I don’t need a 5.0 for its performance, but their interiors just feel more modern. If it was a second car then I don’t think this would mean so much to me, but as I’m planning to use everyday it seems more important (rightly or wrongly...).
    But whether that’s enough to justify the premium is another thing!

    Look for one with the portfolio spec interior if you want the comfort. Even a 5.0L driven daily and sensibly can deliver decent economy.

    the one I’ve identified is a portfolio, “with all extras” too.....

    The later cars have some problem areas ironed out like the A/C duckbill, etc. However, these have probably also been fixed on the older cars by now.

    If you are looking at the non-supercharged cars, the 5.0 will give you near 4.2 supercharged performance with 4.2 N/A fuel economy (if economy is an appropriate word for a heavy V8 ).

    With it comes a stiffer suspension though. You might really want to compare if comfort comes before sportiness. Also, 20" wheels are not essential and even the standard 18" size looks OK while those tyres are significantly better priced. The 5.0 cars got bigger brakes, better active damping, etc, but for daily use, I don't expect that matters much.

    The X150 in all forms was a well made car and are comparatively trouble-free.

    When I was buying I looked at both the 4.2 and the 5.0. I saw several, but none were exactly right for me, for differing reasons.
    When I saw the right one I simply knew I had to have it. It just happened to be a 4.2, but it was simply spot on in colour inside and out, utterly perfect condition, and very low (23,000) miles. I was never going to walk away without buying that car!
    Five years later it is still only 38,000 miles, still perfect condition, and nothing has gone wrong save for 2 brake lightbulbs and one indicator bulb, costing about 15 pounds between them!
