Reborn sold from July 2006 to October or even December 2012.
Prosmatec sold from March 2001 to June 2006.
City Vario shape sold from August 2003 to December 2008.
EJ Civic sold from January 1996 to 2001 April.
3rd Gen City sold from January 1997 to August 2003.
City i-VTEC launched in JAN 09 and will complete 2015 for nearly 6 years.
So officially the 4th Gen City sold for longest time of 6 years and 7 months and Reborn comes 2nd with 6 years and 2 months.
The 6th Gen civic was shortest lived with 5 years 2 months official production time.
The First facelift of Honda was in January 1999 when they launched Oriel Civic.
2nd Facelift was in JAN 2000 with EFi City.
3rd & 4th facelift was when they launched beige interior and eagle eye in June 2003 & 04 respectively.
5th facelift was when Steermatic was launched in JAN 06 with different shape bumpers of vario.
6th facelift was May 2012 with City Aspire.
Beige interior was introduced in September 2012 not technically a facelift but major improvement to the City ugly interior.
In 2008 changed dashboard of Reborn but that was not worthwhile.
So except for Prosmatec the 2 year facelift theory is total flop.
While the 4 year complete change was also never witnessed.
