I remember getting really good mileage in both FI cars (1.8 and 2.0), over 25 mpg in fact. My 914/6 is significantly less, but I think that's a matter of tuning and adjustment that I haven't mastered.
Yes, Pam drives the Bumblebee to the golf course. I remember reading that that used to be one of the criteria that Dr. Porsche required in a car - the ability to carry a set of clubs.
It's cheaper (long run) to find a car with all the goodies already bolted on. Alloy wheels, upgrade to later style transmission, center console, sway bars, etc.
You're on a budget, so don't get wrapped up in that "73 2.0 is the best car ever" BS. First and foremost, the chassis should be free of rust. A 2.0 is nice, but not necessary for a groovy daily driver. Even the
stock suspension, if taken care of, is a very comfortable ride. You don't need adjustable Koni or Bilstein sport shocks.
If you think you even might be tempted to go autocross or rally, then lean towards a 2.0 car (regardless of year, the engines are all basically plug-n-play) with sway bars and Fuchs wheels. You'll be happier later.
Patience (or calling Brad/Rich @ HPH
or Mike Z ) will find you a nice solid car, mechanically strong.
