You gonna love it !
Though, a good 964 is gonna cost you.
If you wanna use it as a daily car, go for Carrera4, its known to be safer and more stable.
For best looks go for Turbo or 964-Anniversary edition (only 911 pcs made).
I don't know much about 911 RS, but it seems to be popular among racing people and thus prices remain very high.
A good 1992 911 RS would cost you around what you'd pay for a new 911 997.
Cheapest would be Carrera2 from 1990, at around $30k.
At least thats the level of prices for 964 in Switzerland.
