Hi Robert,
I have a very nice 1990 C2 Targa (that is in So Cal) that I will make you a great deal on. This car has had all the maintenance done on or before schedule so it doesn't need anything for quite awhile.
You can see it at

I would think if you start with a good car you're not going to be spending much on it only logging 3K miles a year.
