BMW approved used car - breach of contract?

[Z4M-2006]

How old is this 5 series ?

If this car had 4 buckled wheels then surely it would drive like a broken trolley jack

Could it be that there is nothing wrong with the car but someone they know wanted it so cancelled your purchase?

It is either this, or, with 4 buckled wheels means it may have been ‘jumped’ at high speed, affecting shocks, mounts, chassis & has more serious problems.

I would suggest, go visit to politely express your disappointment & ask ‘off the record’ what the real issue with the car is. If it’s considered in bad condition, selling to you who would one day on-sell would cause them future problems... so easier to withdraw

Thanks for all the various responses.
The dealer has now come clean on the issue: apart from a few minor cosmetic issues, the four buckled wheels mean they can't be certain this won't then transpire to have also caused suspension damage etc.
So, yes, walking away with deposit and the hunt resumes.
But I did explain point out to them that: a) honesty upfront goes a long way; b) an apology after 3 days is 3 days too late; c) their contract is not fit-for-purpose for AUC cars in this situation.
In return, they will look out for a car with similar spec and 'do a deal'.
