what were the best years 81, 82 or 83

["snextime" <ionicdesign@xxxx>]

i was wondering what was the best year delorean produced the dmc-12
1981, 1982 or 1983? i heard the very first ones of the 
assembly line had door fitting problems and the most were made in
1981 and the least in 1983 but is there really a year or vin 
number sequence (example.. between vin # 3500 to 6000 for the 1981
years) that is better built or are they really all the same 
or was the worst or best built in 1983 because of the factory closing
and the workers were more skilled because they have 
assembled more cars by the factory closeing in1983?

thanks
