Mk3's still had latch type door catches in the 80's, anti burst door catches had been a legal requirement on new designs since the early 70's, they did bring them in on the 90's though.
Sliding windows, no power, uncomfortable, many design flaws, the list goes on and on
About the only thing they have going for them is the fact you can take back/front/middle from just about any of them and put them onto a modified chassis and the panels are aluminium so they last reasonably well, but the chassis doesn't last unless it's looked after, even then I've seen them rot out in very little time.
Good for making an off road toy from and after bending/scratching every single panel you know it's not going to have a huge rusty hole in by next winter
Can you tell I'm not a fan
