If you have £35k to spend I would say:
G29 Z4 (30i?)
The very best E89 35is and some change
A real Porsche (911), 997 facelift either tin top or vert with all the toys and good mileage
OR if you like standing at the side of the road waiting for recovery, go for an F-type.
It's a bit flippant I know, but have seen many, many threads on car forums where people have given up on F-types due to their reliability issues and poor quality.
I'm not sure about Jaguar as a whole, there more recent stuff though is pretty solid. Having had 3 F-Types they have all been brilliant, I had a light come on due to the catalytic converter on my AWD R but Jag sorted it for free outside of warranty, and accross the 3 dealers I've dealt with they've been pretty awesome, actually my best dealership experiences... they could give out better courtesy cars though

Driving home in a Fiesta 1.0 whilst my V8 is in for a service was strange xD
Material quality is good though, better then a newer Porsche? No, well... they're definately better then anything that came before the 991 and 981's. The interior quality was also bumped on the R coupe and all MY2015 cars and got a further bump in MY2017 and MY2019.
On earlier RWD cars they did use some crappy steel on the rear frames which could rust, I didn't know this going into my V6S so never checked it, but going into my other 2, a 2014 V8R and a 2016 AWDR, I got them inspected by Jaguar and they were showing some slight corrosion, nothing a quick blast and spray wouldn't fix, but they were a long way off needing that.
Have a play though, everyone has and recommends a Porsche, after selling my Supra and went on the mooch again and a Boxster/Cayman were on the list and everytime I get behind the wheel of one I come away unimpressed with the overall experience. Yes they handle well and they feel well built, but you almost never get to exploit it's full capability on the road and ones in this price range come with a lot of empty buttons which annoys the crap out of me xD I guess they're more practical and against the V6S their residuals will be better (although you'll probably be paying more for the car and you will pay more for servicing etc...).
I do like the G29's, the M40i is a blast, not driven a 30i, sitting in one it essentially felt identical to the M40i, they're still fairly new though and will depreciate a chunk...
All said... I'd get the F-Type... they objectively look better
