My MINI One had mechanical failure in March, just before lockdown. It was towed to the dealer that I bought it from, who quoted £1800 just to open the bonnet and say what was wrong! From reading various forums, this looks wildly disproportionate for a diagnostic check - especially from the dealer that we bought our second car from. The car was worth £6000 and we have £3000 finance to pay off, so I don't know whether to accept a derisory trade-in offer of £1500 or find someone else that might be able to fit a new engine at less than the value of the car.
