Again, ditto on what Scott said. We did H20 Pump, Timing belt, Thermostat, Balance belt, plugs, DME, Oil change.
Flushed out fuel lines, Brake lines & clutch lines and tires, all before we started it...Do some serious homework here. You didn't say the asking price...I paid 5K for mine, and have so far put 9K into it...Make sure you look around online for comparable cars for sale...There was a showroom fresh 95 with only 15K on the clock that hit 21K online and didn't hit the reserve.
After doing some online homework and some forum lurking here, I figured the car was worth 17 - 20K. I figured It was going to run me 10k to get it on the road and so far the car has not disappointed me....I still figure it's cool, because many of the ones I have seen at dealers are in the 16 to 17K range.
Figure your budget too....if you have to put cash into it in large quantities, it is maddening to have a beautiful Porsche in the garage and at everyone's shop and not be able to drive it! I can talk of this personally. Since I bought the car, it has been weeks at two different shops and then weeks in my garage waiting to get back into the shop...It will however one day all be worth it..Once I get all the new stuff (valve cover gasket, fuel gauge, odometer, and temp issue) solved I still need to put on my strut tower, firewall, and castor braces, then front end alignment.
Keep researching....and good luck!! This was my first Porsche and I think I am hooked!
