Whats going on next door ?

For several years I have watched the cars of people who stay at a holiday house next door. They are often a wide range of vehicles, though they are rarely new cars they are generally relatively flash, and interesting... so when four large dour looking prestige saloons were parked up, all in dreary colours showing little flair my attention was aroused. All four cars were different makes but all sported the most drab lifeless colours possible. The saloons had no flair of passion to them despite being an Audi, a Mercedes, a VW and a BMW. A general lifeless aura hung over then. What kind of occupants all drove such vehicles ?  I'm fascinated now at who they are and why they are here. These are not the usual cars that families arrive in. There is no kudos to them. They are overly dull and hence stand out. This is the way my mind works. This is what alarms me. It appears almost sinister. Maybe ive watched to many films ? lol
