I have just bought a new 30th anniversary GSA with the premium pack and love it. I test rode an 08 plate GSA and found the engine crude, lumpy and lacking some oomph. The new bike is much smoother at lower speeds, has great torque that almost had the missus off the back when she wasnt paying attention and has lots of top end. I have only 250 miles on the clock but I have been away on holidays and have only been playing for 2 days !
The panniers are free but you have to pay for the frames if you don't have the premium pack. I also worked out a deal so I got the 30th anniversay and an alarm for a discounted price at Alan Jeffries thanks to Paul their new sales guy.
The 30th anniversary colours also got lots of looks at Squires when I popped up the other day with a few 'power rangers' asking about the bike

I wish I'd got a free top box, inner bags etc
