Buying advice 911-oldie

Hello, I’m just thinking about whether I should fulfill my childhood dream and get an old 911. I’ve been reading through dozens of forums for a year now, and I’ve also had a good theoretical knowledge about the different models, engines, etc. and what to look for when buying. Last week I was in a sales room by looking at a model that was interesting for me. The car looks very good. The car was rebuilt by a specialist workshop (sport car Eiden, if I am not mistaken). Next week I will organize a test drive. The car is restored and no longer original. This has disturbed me at first sight, but could accept me if the price is in order, since the vehicle is primarily for driving and not for collecting. The facts: Coupé Year of manufacture: 1976 Engine: 2.7 with other pistons (performance on the test bench: 195 ps) overhauled Carrera rs Look No Matching Numbers Clubcage Car originally comes from Switzerland 915 transmission with shorter switching distances Original seats replaced by 2 shell seats Bilstein suspension New tyres 1 year dealerga rantie Price: € 27,000 (in my opinion too high) Photos here:http://www.fineyoungtimers.lu/fr/2/top-menu/inventory/0-inventory-30/ I thank you in advance for your answers!!! clency
