I only ever owned one Maxi, Hobsons choice, it was the last car though an auction and I needed to get home about 30 miles. It came with 4 new tyres (remoulds) and a fresh MOT, but on getting in, the drivers seat backrest collapsed and the handbrake lever was not attached to the floor by much. The gearbox was noisy and the engine blew up 10 miles from home. So eventually I got it back, fitted a scrapyard engine and box and fixed the seat and the handbrake, went to fill it with gas for a trip to London and the tank leaked 7 or 8 gallons of gas all over the forecourt. So another tank went in it and it went in the next auction, i took a loss, but was glad to be rid of it!
This experience may have coloured my opinion of Maxis, i'd never buy another!
I've had similar experiences to your's in auctions, but in night clubs instead though, and usually minis rather than maxis!
