I'm poor.
That is why my "luxury European GT car" choice would be a Jag XK8. Cheap to buy, cheap to repair. For about the price of a nice G-body you can drive a $70K in the 90's DOHC all aluminum V-8 European convertible with leather, climate, power everything that gets 24 mpg on the hwy. Good paint body LS Swap candidates needing a motor or trans are $1500-$2500, but very good running/driving cars are $4,000-$6,500.
They rust like no tomorrow, so get a nice southern one. They are scary on slick roads, some northern ones could be still good, but its a crapshoot. Jags have known "issues" which is why they are cheap, but these issues are repairable by any competent DIY mechanic with tools... which isn't 99% of new Jag buyers.
