Hi John,
Agree with a lot you comment on, Plate lettering is a taste thing and subjective I suppose, SL55 exhausts simply don't fit kit mouldings, ones on are best we could get at present. They may well change, just the aesthetics that is.
As for badges, she didn't have badges on at all, straight after kit went on, couldn't go anywhere without being stopped and had to endure all sorts of tiresome, comments that went as follows:
"suppose its a 350 done up eh?"
"what is it?"
"Which kit is it and what have you done that to a 350 for?"
So we put SL55 Badges on:
"Thats not a 55!"
"Bet its a 350 with badges on?"
and just about every other "stupid" comment you can ever think of. I couldn't be bothered eventually.
Thus, far better to just stick SL65 badges on. As you quite rightly say, those in the know; know it aint right, cabrio roof, oval rather than square petrol cap, non standard wheels, does rather give it away. All the others just nod appreciation and believe what they want to believe. If they ask, they're normally lovely and we have a great discussion about all the work done, really enjoy the crack.
As for the sound, in my opinion and that of many others, having had the exhausts, headers etc seriously worked and audio tuned, over 3000 rpm its quite simply a symphony. Cheers P
