My own observation around these here parts--the characteristics one might consider "Heat Score" and those attracting Squid attention seem to be pretty similar as a general rule. The AMG mods look great, but my banker's-anthracite-gray dead-stock look feels even better as I note how little attention it draws from either squids OR gendarmes. Besides, the gray goes with my early-50's hair and mustache....
