Hi, I tried to pull away this morning and my car wont move.  The front end
seems to start to pull away (making the rear of the car dip) but it just
wont budge.  

 I haven’t moved the car in just over a week and the weather has been
quite warm.  I tried putting the car in neutral and pushing it, but it
still wont move.  I wanted to try to reverse to see if that worked any
better but someone has parked right up my arse (as usual) so that’s not
an
option until they move.  I figure something has seized but that’s just a
guess.
