may i repeat and quote gary1910 posting here in full:

Leopard_2A4---surplus Leopards are being sold at "fire-sale prices"
that can hover in the $1 million per vehicle range, as opposed to
the $5+ million per vehicle one must expect for modern Western
contemporaries.

Singapore's AMX-13 SM1--The new arrivals of Leopard_2A4 will
complement existing force of 300-350 AMX-13 sM1
tanks, a heavily modernized version of a 20-ton tank
designed for paratroop support that saw extensive action in the
1967 Six Day War.
How many would believe that sg has 300--350 AMX-13 SM1?

Singapore's Ministry of Defence has announced that they intend
to strike an agreement with the German Federal Ministry of Defence
for the sale of 96 Leopard 2A4 tanks (66 front-line, 30 spares)
plus training and supporting equipment from the German Armed Forces
to the Singapore Armed Forces. SAF soldiers will be trained by the
German Army to operate the tank in the later part of 2007.
Singapore Today Online quotes Defence Minster Teo Chee Hean as
saying that the first Leopard 2A4s will enter service in about a
year or a year and a half. "We looked at a number of different
alternatives and the German offer of refurbished Leopard tanks is a
very cost-effective option for us to start replacing some of the
SM1s." Given DID's past coverage of Germany's Leopard sales, this
point is hardly surprising; what might be surprising is that
Singapore plans to keep its upgraded 1960s-era AMX-13s in
service even after the Leopards arrive...
As Defense News noted back in a March 2005 article:
"How dramatic the [German] Army's transformation really is can be
seen in Structure 2010, to be adopted as of 2007. The service will
reduce its fleet of main battle tanks from 2,528 to 350, infantry
fighting vehicles from 2,077 to 410, artillery pieces from 1,055 to
120 and helicopters from 530 to 240..."
While price was not disclosed in the Singapore deal, the surplus
Leopards are being sold at "fire-sale prices" that can hover in
the $1 million per vehicle range, as opposed to the $5+
million per vehicle one must expect for modern Western
contemporaries.
Even the far-inferior T-72 has difficulty competing at this level,
and the only thing keeping Leopard sales from jumping far beyond
the European continent has been restrictive German arms export
policies. Meanwhile, entrenching the Leopard 2 as the "the
Euro-LEOPARD" may offer other future benefits for German
industry.

Singapore's AMX-13 SM1
(click to view full)
The new arrivals will complement the existing force of
300-350 AMX-13 sM1 tanks, a heavily modernized version of a 20-ton
tank designed for paratroop support(lionnoisy note:read my
yesterday posting fo JDW confirmation for the number) that saw
extensive action in the 1967 Six Day War. Singapore has made
updates and ongoing improvements to these vehicles something of a
local specialty, running refurbishment programs in the 1980s and
1990s [see PDF for full modification details].
Defense Minister Hean has stated that the SM1s will be kept
in service even after the Leopards arrive. While the
Leopard 2A4s will be significantly superior in many respects,
including electronics and networking options as Singapore pursues
its "3G" force, the SM1 has three things going for it.
Numbers game
One is that numbers can still be useful on the battlefield.
already up graded
The second consideration is that the improvements made to the SM1
have kept it in shape as a capable combatant relative to
neighbouring threats.
mobility
The third consideration is that the AMX-13 SM1s' 20 tonne weight
gives them mobility options that the 62 tonne Leopards can't
duplicate, and make it especially useful given Singapore's
environs
