Mikey914 makes nice repro bumper tops.

Wheels look to be the real deal. Use a gentle detergent. No foul for a little patina.

This evening I finished working earlier so I had the time to do a one hour testdrive. The car feels really stable : no squeeking, no strange noises , no "bending" of the body while cornering.
I didn't put the pedal to the metal yet ( max 4000rpm), because the car has been standing still for 4 years, so I'm gonna take it easy. The engine has power, but sometimes it holds in for a second. Could be the fuel pump or the injectors or the EFI? I don't know. I'll try again later this week. Maybe it's the heat? Today it was 31°C(88°F) which is very unusual for Belgium.

Hi slotty. Greetings from the Netherlands and good luck with the 914 !
Yes it was hot...but the car came from california and was restored and tuned by previous owner you mentioned...so that means it is used to these temperatures.
it was not driven a lot the last year I understand from the story....first try to drive it a bit more to see what is really going on.

I took off one of the wheels. This is the inside.I see a VW logo.

Stepping into unfamiliar territory, but I believe the "914.xxx..." part number indicates real Fuchs.

Here's one of my 2.0 Fuchs. I could be mistaken about the fox logo on 914 wheels. Maybe they are only in 5 bolt wheels. Anyway, yours look real.

They look the same to me. Good news for me!

Yes those are real, I believe the fox head is stamped beside the VW logo.... and I believe they were all stamped by a 7 year old girl.
