Looking at getting another transit. Have a 51 2.0 di atm but it has 200k on and things are starting to go wrong so want to get rid while its still running etc

Was look at getting another one the same shape but with lower miles etc

Ive seen a mk5 transit 2.5 banana engine on ebay mint 66k 2 owners completely clean for £1500

My mate always goes on how good they are reliability wise but just how much they rust! This one is immaculate by the looks of it!

Is it a good idea to downgrade or not?
