I bought a used Z4 last week. Really like it. Discovered 3 small problems, bumper had a smart repair carried out at BMW last year by previous owner and it was really poor quality, tracking was out slightly and as they fitted 4 brand new bridgestone runfats i didnt want to risk uneven wear and finally there was a small clip missing from the soft top hing.
I contacted Harry fairbairn BMW in giffnock where i bought the car and had it booked in. Dropped it off at 8 am this morning, had a nice cup of coffee and a scone and left with a brand new BMW 116i m sport, twin scroll turbo, fully loaded.
Got a phone call around 3pm to tell me my car was ready. On arrival another cup of coffee and service advisor said sales had agreed to foot the bill for the tracking, missing clip and there going to paint my full front bumper in there own bodyshop, result!
Anyway got my car booked in for the work and when they brought my car round to me, it had received a mini valet, all fluids topped up including oil, tyre pressures and wipers checked and a nice air freshener.
Quite a good service i think. Also they said if i dont need a courtesy car next week they will pick my car up and drop it back to me.
