The 348 is a fun car, has nice styling. I had to laugh when someone above said the 993 sounds better!

.....
The 348 is not particularily fast, nor is a 355 (because they are hard to drive) but they sure look nice and have great motor sounds.
The 355 is far better looking (especially a TB) than a 360 in my opinion....
But, price out a service on one, that will keep you driving P-cars!
Cheers
