Car appreciation... the aesthetics, the engineering, etc

It’s never “just a re-gas”.

Correct. A/C systems can be a complete money pit if someone who doesn't know what they're doing has had a crack at fixing it. So many compressors have died on my previous cars due to past cack-handedness.

@Fox get a reputable Honda place to look at if you can. At minimum and hour of labour will be ~£90-£120 and gas could be another £50 (R-134a). If the seals are gone in the system those numbers only go up.
