Not quite - if we're going to do some maths, let's use accurate figures
1. New GT is £29K. With 19" wheels, metallic, and alezan leather, it's £31K. (actually £31,050). This is what is rumoured to be offered on the GTS, along with some bodykit mods (let's hope it's not that horrid Strosek monstrosity).
2. The Novodem SC would currently cost you £6,500 fitted in Switzerland, with their own warranty. Assuming the same price here.
Total : £37500. Hence the all-in price seems quite realistic - and especially good value if it includes a UK warranty for any UK Nissan dealership.
I just want to know which other 'must change for reliable FI bits' - plugs, oil capacity, fuelling upgrades, clutch - they'll throw in too.
