Dad drives a Seat Alhambra automatic TD. One thing to watch is the type of oil used in VW range of cars with the turbo diesel engine, the oil is incredibly expensive, and even the forums do not recommend an alternative. Sorry cannot rmember what the oil spec is at the moment (at work) also auto box oil is funny again.
And yes the new ones suffer from failing auto boxes just like the older one. Also watch for electric windows and central locking not working on individual doors, usual is broken wires between door and door post.
Unless you have a very young child avoid the built in baby seat, it is horribly uncomfortabe when folded down for anyone else to use.
I find build quality not up to standard, and unless under 3 years old expect no help from dealers.
If you have to remove a door panel for access to window motor etc, you will break some clips, not to bad as they do glue back on, but certainly a problem.
Also be very wary if it does not have a radio fitted. It took us months to get one that just plugs in.
Personally I would avoid the Alhambra/Sharon. Might go for newer Galaxy as not the same as VW base.
