In the UK the difference is more like £7,000. For that you get a bigger power difference (170 bhp vs 140 bhp), stiffer suspension, Record Monza exhaust (if you like it, I don't really), optional (free) heritage black bonnet/boot (hood/trunk), plus Abarth badges, seats, red bits if you want, etc.
Much more difficult to justify IMHO...but a silver/grey one MT with all red bits is growing on me...
