My girlfriend is looking for a parallel import 06MY 2.5 WRX in Metallic Black. We have read all the pros and cons of buying parallel and shes decided that this is the right way to go. The only question is which supermarket is better for getting this particular car?
I have looked round a few websites and called several supermarkets to find the following:

Motorpoint have the cheapest price £14999 cash but no black cars in stock in the forseeable future. I have read some bad things about their service and forwarding of documents such as log books on scoobynet. How do members rate Motorpoint?

Alliance - £15995 - have plenty of stock, will they reduce the price a little more for cash?

£15495 at Motordepot, can be had for £14495 but you have to purchase using their finance agreement so the cash price is still £15495!

Litchfields are more expensive again.

So what is the solution, where is the best place to get the car from???

Cheers
Ben
