They are pushing the gen1 cars from stock with heavy discounts as there are gen 2 now available and although there are different opinions, I would advise you to get the gen2. They are available (I have a red one that was delivered within a week of order, but only after I insisted that I would only order the gen2, they then magically produced it).
You are only waiting for the car a few weeks / months, but will be driving it for years so be patient and make the right long term choice for you.
Do also check the affinity scheme as you can also get £2500 off the price of the gen 2, if you dont currently qualify, you can join the mg owners club for £50 which does make you qualify.
