You could look at one of the last couple years of the second generation f-bodies, namely the Trans Am. I actually prefer the look of the later year third gens, mostly the 88s-90s. Not of fan of the front end of the 91 and 92 model. If you're handy with the wrench, there is a ton of info out there of swapping in an LS based engine into the third gen f-body. You need to modify your motor mounts, but there are a few places that have them for sale.
OT- Classic Cars
1993 Mustang Cobra. Definitely a collectors item, and can pricey with low mileage and good condition. A clean 5.0 LX would be the cheaper alternative. I also like 85 mustang GT. Same look as the LX from 87-93 but without the ground effects that they put on the GT in that era.
Also agree with the 1987 Grand National. Cutlass Salon was also a sweet ride but it would proabably be tough to find one in good shape. And obviously, can't go wrong with a Corvette anywhere in that era. 1990 ZR1 has my vote there
