Just a random thought leading on from this and maybe one for a new thread
who has/knows of the highest mileage S30 here in UK or on forum ?
I’ll start, a 280Z passed through my hands that had a known 218k miles with full history from new so no doubts on authenticity, was still on original L28 and in excellent shape so goes to show if they are well looked after and rust not an issue they can easily achieve high mileages.
Highest mileage cars will be warm climate imports (US) where cars have never been off the road for any length of time and average yearly mileages much higher than our own due to large distances between cities, states etc. However, more often than not there is insufficient history with them to be sure of overall mileage, you are just looking at a figure on the odometer.
In the UK I would put money on fact that most S30 cars sold here never saw the odometer turn over 100k miles. Rust made sure the body and chassis failed well before the mechanicals ever did. Hence would be logical to expect there are quite a few relatively low mileage engines knocking about.
