Hi Kevin,
I took out a extended warranty on our 2000 Avondale Golden Mayfair,We had already had 3 new water pumps,2 new sink worktops,cooker door,new wash-hand basin,sliding door to bedroom repaired,washroom resealed and various broken catches replaced. This was all within the normal 3 year warranty period.
We are no way heavy handed with our van and this was just normal use!.
I was glad we did take out the warranty, because just before it expired the floor around the sink-unit started to de-laminate and the shower tray cracked.
So as you can imagine the repair bill would have far outweighed the extra cost of the warranty.
Hope this helps to make up your mind if it is worth the extra cost or not!
Regards Nidge
