My last datsun was a 1200 ute with rust from wheel to wheel in the sills an checker plate to cover it. a previous owen was amazed it was still going
he had rolled it blowen 4th gear an sized the engine he recons it sat on 150km/h from newcastle to scone (2hrs). But some one since then had bogged the roof so it looked quite normal an replaced the engine an gear box. the diff had a pretty sick noise in it to.
any way it would still hold 140km/h for me an it lasted me 2 years(temp gauge worked only in the last 6 months) of constant abuse i estermate it did around 15,000 km when i had it cos the speedo was inaccurate.
i had 2 minor traffic accidents in it the last bent a tie rod or some thing so you had to drive while turning the wheel abit. it also boiled a few time i think
one particular time i was having a bit of a bash round the bush an went down a 4m long dip with water in it. ripping through i found out it was a little deeper than i thought in fact when it finally got bogged the water started coming in the doors
when i returned with a mates HQ to pull it out the water was touching the bottom of the seats
i drove the car for a year after that. DATSUN ARE STRONG. well that one was. its now in sydney still going strong i guess
