The C5 onwards was when Vettes got really good and even though they still run on leaf springs the handling and ability is great!
On the C6 the Z51 handling pack is worthwhile having, bigger roll bars, brakes etc.
Good points, engine, looks, noise, reliability, performance, handling and rarity.
Bad points, economy, plastic body parts, interior average and if it breaks you either need to be good with spanners yourself or take it to a specialist which there are not many, but they tend to be reliable.
They are great cars, if you can stretch the budget and actually find one the Z06 is an absolute master class.
