The swirls and fancy bits are a royal PITA, since they're mainly stick-ons. On the rig I have for sale, they're peeling a bit and have discolored in some areas. I guess at 12 years old, some discoloration is inevitable.
If I were to buy new (fat chance), I think i'd go for a two-tone scheme, dividing the colors at the house floor line on the outside and maybe doing the above roof-line area the same color as the lower section. Might look like a roast beef sandwich, tough!
On reflection, isn't it odd that "fat chance" and "slim chance" mean the same!
