The decal's wearing is quite common on the Getaway's unfortunately.

BUT the good news to that is that insert decal kits are available.  Just be aware that some kits out there don't have the white highlighting around the numbers - as some printers can't print white (like your home printer).  I would advise against getting the decals without the white highlighting as it is very dull and does not look right.
I did the ones on my T2 which came up really good (have a look at my resto thread on it! - shameless plug).

I found the only place which did the correct decals is http://www.classic-arcades.com/NEW-STORE/index1.html?products.html&1

Just also be aware that some times the graphics can be out of alignment / colour too.
