The tempting thing to do on this car is a reverse upgrade -- aka the Punk My Ride. This is where you leave the LS1 adapter kit at home and drop an entire C3 Corvette front clip on to the chassis...but keep the Jag inline-6 and steering gear/suspension. It is the ultimate in car-mullet -- a C3 Vette front mated to the E-type rear -- the Jagulette. KBZ -- I need a Jagulette badge STAT!!
This is a late Series 1 2+2 fitted with the optional automatic gearbox (a 4-speed manual was the only transmission for the roadster and 2-seat Fixed Hardtop Coupe), but some of the later cars are known as Series 1.5 as they have some of the upgrades from the Series 2 cars. I am no E-type expert, but I'm sure that, even though someone Chernobyled the front end, there are many experts who can tell the difference.
