There are some great ex-military aircraft up for grabs over here in the USA for those with the means. For instance, this immaculate TA-4J Skyhawk - which has undergone a 50,000 manhour restoration - was on display at Palm Springs Military Aircraft Museum in May 2013 for sale at $2.95M. It had previously been advertised for $4.5M so they might be open to offers !
