Most don't care two hoots to be honest.
Most people don't have a clue whats new and whats old.
The plastic pigs alot of folk don't actually like because they don't look like an aircraft that they percieve. High wings also are less favoured than low wings. Also the auld tin cans look more robust than the new machines mainly because they are.
Stick a new shiny paint job on an aircraft, new carpets and a seat refurb and 95% of the clueless will think its spanking new. The fact that the engines compression are on the limits and all the filters are blocked on the vacum system is neither here or there.
Yes there are folk out there that have an eye for the bling electronics but most especially in scotland when given the choice of bling or paying less money per hour will always go for the cheaper option.
