yeah thats the point.. its like a full cosworth replica on book as 1.6L you carnt insure it correct like the sierras with v8s in as soon as u say its a 3500cc etc its like hang on its come up as 1.6 base once you say engine is changed its like there want reports and all kinds.. but like said you carnt insure it as 4dr saloon and its a 2door hatch you no.. but im sure back in day you could change body type hence the f reg 3doors and some e reg ones people claim are 100% but the vin in engine bay says body type but logbook can still say hatch but the vin will code as saloon..
