TL; DR: Brakes discs, pads & Calipers done (weren't really needed, except for 1 rear that had seized) dished out another 100 to the garage to get service and missing panels fixed done.
Had my car patched up yesterday at the garage that my seller recommended. They did the brakes for me and guess what they said about the condition about my brakes....All 4 discs were fine, they did not need to be replaced...only 1 caliper had sized up so they were confused as to why I was asking for both the rear ones to be replaced...surprise surprise..
I had my face buried in my had's most of the time while the rest of the time was freezing my #$$ off..
- Apart from the brakes I had planned to get a couple of missing panels fixed (wheel arch liner & engine under tray, sourced from a breaker in Leicester) as well as getting it serviced, So guess the car is good to go for the remainder of this year.
Oh, and the seller asked me to dish out 100 pounds to the garage, cause apparently, I was asking for way more work to be done on it than originally estimated (panels and service etc.)
...To be fair to the guy that sold me the car, he was nice enough not to cross question the garage about if indeed the work I asked was really needed or not.
All in all, this whole experience has taught me some valuable lessons about car ownership & maintenance.
Thanks to everyone that contributed.
All that's left now is to have my old calipers returned to GSF for my deposit back.
