Having said that, if they give thier fleet some TLC inside and out, I'm sure many members the fleet could reach that age without issues.

Modern buses are rattling to bits within weeks of hitting the road nowadays. You are right, with the correct level of TLC any bus should reach 20+ years, most operators will work to around 15-18 years life expectancy. After this time, vehicle is normally fully depreciated.

Some will live on, but a major until failure will usually mean withdrawal.

Some operators use fully depreciated vehicles on school work, as the prices are usually very close and it can be the difference in winning or not.
