Picked it up today...I dont doubt its flawed and as already said seems to be a mismatch of Omega stuff Vectra stuff and so on...Battery and location to say the least seems a bit of a challenge...
However that said, forum reviews seem to suggest that despite its flaws people like it...its a lot more roomy than the Zafira, has a good 3.0 Omega engine in it and from my point of view, it was VERY cheap (could easily sell the engine for more than I paid for the car!)...the supposed possible HG failure seems to be a failed header tank pressure cap and rattling tensioners which doesnt bother me at all as I have replaced the cap with an Omega one and can get new belt and water pump fitted for £175 including the belt kit) so years MOT and nicely running 3.0 v6 engine and away I go

If I had £2k to spend on a 7 seater, cant say I would buy a Sintra...but for sub £500 for a 7 seater with a years MOT and timing belt sorted...I'm not gonna complain...
Think I will look into getting the battery adaptor you can apparently get to convert a decent normal battery to the required terminals for the Sintra but fingers crossed it will do me for a while till I can afford something better and if nothing else I can easily get my money back at the end of it
