Note - Car is in Europe

Does anyone have any recommendations to take my car to have a freshen up in the UK? . It is a 1992 Sapphire Cosworth, Spanish new and lived there its entire life. Totally rust free, aircon car etc and has 109,000kms with service history. Things are starting to get a bit rattily in the interior, minor electrical gremlins, niggles etc but still used regularly. Just started to feel a little tired and I'd like to have it done properly as it is a non messed around, standard car.
