If you had a mortgage then the extra £12,000 over 4 years for being about to leave and extra say £50,000 to £60,000 on the house probably means saving the same interest on your house as you are spending with Morgan. So not a bad deal but I always had the idea to only borrow for a house, pay it off and save up for cars, especially toy cars like a Morgan or Frontline. Lots of fun but really a luxury that borrowing for never made sense to me, however the younger generation seem happier to borrow than I am.
Back to the bike, I spent more on my last bike that the Pashley but cycling is a hobby and I like nice bikes, I have three bikes, Scott Spark dual suspension mountain bike, Fat bike with 4 inch tyres for the beach, desert trips and a road bike, both the road bike and mountain bike are Carbon fibre. The Pashley would make a nice commuting bike but looks overpriced for what it is.
